Poor poor service!!!!

I livr in rural area with poor signal. Due to numerous accounts i hold vodacom installed a booster some years back. This worked like a charm. 4 months back the boosters stopped working. I reported and after weeks a technician arrived to repair. On day repair i told him its still not fixed. He blaimed the local tower and undertook to repair. 4 week back i reported again. Call centre said it will take 6 TO 8 WEEKS TO SEND ANOTHER TECHNICIAN. It now is 4 weeks. No technician, no signal and no service. Shocking and appauling and the thinck i spend hundreds of thousands with them over years!!! I suppose time to get rid of vodacom. Any suggrstions on better service providers!
